numComponents
- Number of components to extract from the data, must be greater than zeroresult
- Vector function that maps the input space onto a numComponents-dimension
Vector representing the directions of maximal variance (information
gain). The i-th row in the matrix approximates the i-th column of the
"U" matrix of the Singular Value Decomposition.public AbstractPrincipalComponentsAnalysis clone()
AbstractCloneableSerializable
Object
class and
removes the exception that it throws. Its default behavior is to
automatically create a clone of the exact type of object that the
clone is called on and to copy all primitives but to keep all references,
which means it is a shallow copy.
Extensions of this class may want to override this method (but call
super.clone()
to implement a "smart copy". That is, to target
the most common use case for creating a copy of the object. Because of
the default behavior being a shallow copy, extending classes only need
to handle fields that need to have a deeper copy (or those that need to
be reset). Some of the methods in ObjectUtil
may be helpful in
implementing a custom clone method.
Note: The contract of this method is that you must use
super.clone()
as the basis for your implementation.clone
